Here is one way to check head light aim
OK, since I really think this issue needs to be addressed I'm leaping in to frying pan.
I've been at a disadvantage not knowing what the lights looked like because I had not driven after dark before the fairing was rebuilt after the deer collision. I checked various web sites for ideas and the New York laws and regulations for headlight rules. I didn't find anything official so I went with advice that made sense to me.
Here is the procedure I used to aim the headlights:
"Find a flat patch of ground with a white or light-colored wall at one end. (You may have one of these right there at home--it's called a driveway.) Place the bike 25 feet from the wall or garage door . Measure from the center of the headlight to the ground with the bike level. Now go over to the garage door and mark one line at the same height above ground, and another two inches lower. Use a carpenter's level to draw a horizontal reference line.
Switch on the headlights and mount the motorcycle. The low beam's upper cutoff point should rest right on the lower line. Because most bikes have combined high- and low-beam reflectors, setting the height (and checking to see that the beam is centered along the bike's long axis) is about all there is to it. But if you have separate high beams, make the center of the high beam land on the upper line. That's it."
I measured the middle of the CTX's low beam to be 35.5 inches. I used a strip of 2 inch wide painters tape as my marker taping the top of the tape at 35.5" to wall of my shop. So I adjusted the low beam lights to the bottom of the of the tape. I found mine were probably 8" low. The LED's put of a nice flat light. Easy to see and adjust.
There are two adjusting knobs. Finding the adjusting knobs is hard and they are hard to get a hold of. Check pages 3-18 of the service manual or page 155 of the owners manual. I put the bike on the center stand, turned the wheel all the way to one side in order to get my big mits up under the fairing. Did one side at a time this way. In this position, I could push the knob with one finger a little each time. Clockwise moves the beams up, Counter clockwise down.
The beams were well on center, so I didn't need to adjust that, but there are two philip screws to adjust left and right.
I'll post back with my evaluation of this light position in while. Hope this helps.
